What StyleGPT captures from your writing
What StyleGPT captures from your writing
These are the core signals StyleGPT pulls out of your samples and encodes into your guide:
Vocabulary Level
What level of language do you have? Which words do you use more. What industry jargon do you prefer
Tone & Attitude
Are you direct or diplomatic? Warm or dry? Intense or laid-back? StyleGPT identifies the tonal words and patterns that define your vibe.
Voice & Perspective
Do you talk in first person in your writing or third person? If when you talk in first person, how much emotion do you attach to your writing.
Sentence rhythm
How often you write with short lines vs longer ones. Where you break lines or use questions to create momentum.
Structure & formatting
How do you open a piece, build arguments, or close your ending. What are your habits with lists, or bolding, or punctuation.
Style guide export
All of this rolls up into a style guide any AI (or freelancer) can follow to match your voice and brand.

Every time you think “this draft doesn’t sound like me,” you pay a hidden tax in rewrites, lost trust, and inconsistent brand.
- StyleGPT lets you do the work once, by uploading real samples, and then reuse that “voice DNA” across everything you write.
- Feed the guide into AI, and your first drafts land closer to final, instead of starting from generic.

"He also built a custom GPT tool for me to use so that page outcomes can remain consistent in reading level and overall quality. All of this took a little under four hours! He was professional, cordial, prompt and the final product has been great! The GPT is very effective at bringing the reading levels down to what I need then to be, and is flexible to use. I'd recommend working with 4Fsh if you're new to AI and need assistance understanding how best to leverage it in your work."
Jazz B. Head Law Librarian @ Brockton Law Library
"...I was going to say your prompting tool saved my team 1 month of work this week [for a] government proposal..."
Nate R. Marketing Manager
"As a User Researcher, I could not figure out how to prompt an AI model to do a complicated quantitative test, as my attempts kept giving results with data that I knew was wrong. Working with 4Fsh, I was able to quickly get a methodology that gave a reliable, accurate output for use in my academic work. The team was professional and easy to work with, and I highly recommend working with them."
Tiffany K. User Experience Researcher
"...I love it, thank you. I love using this tool now. 4Fsh is really useful."

Frequently asked questions
Frequently asked questions
What does StyleGPT actually do?
StyleGPT analyzes your existing writing and generates a style guide of how to write like you, without the em-dash.
How do I use it with AI tools?
You upload your StyleGPT guide into any prompt or automation and tell the model to follow it exactly. It works with any AI tool that accepts uploads.
How many writing samples do I need?
We recommend at least 15 pieces of writing. Email, posts, articles, sales pages. The more variety you give StyleGPT, the better it can map your full range of voices.
Does StyleGPT write content for me?
No. StyleGPT builds the style system that lets AI output sound like it came from you and not someone else.
Can my whole team use the same style guide?
Yes. You can add the company's brand value to the style guide, so every time you use AI, it sounds like it came from the company's playbook. Or you can use it to make the better employee's writing the standard for all team members.
What if my style changes over time?
You can re-run StyleGPT with fresh samples whenever your writing evolves. That generates an updated guide that better reflects how you sound now.
How accurate is the replication?
With enough diverse samples, most users get to the point where drafts feel 90 to 95% like their own voice. Small edits finish the job.
